Windows 7: Computer freezing randomly for half a second!

Computer freezing randomly for half a second!

Hello everyone!

I have an issue with my computer that I can't seem to solve. I have tried a few things to get rid of the issue but none of them seems to do the trick.

My computer is freezing for half a second as stated in the title, and on a daily basis for the most part. The sound is also freezing causing a "brr" sound. (The sound usually changed depending on the sound coming through the headphones/speakers)

What I have done so far:
-Updated a ton of drivers (and flashed bios)
-Scanned my system for malware and viruses with MSE
-Ran a memtest with Memtest86+

Tower - Coolermaster Elite 430 Midi
GPU - Asus Radeon HD 7950 3GB "DirectCU II TOP"
PSU - Fractal Design Tesla 650W Standard
CPU - Intel Core i5 2500K Quad Core 3.3 Ghz
SSD - Kingston HyperX 120GB 2.5" 555MB/510MB
OS - Windows 7 Home Premium 64bit
HDD - Seagate Barracuda 1TB 7200 RPM
MOBO - Gigabyte GA-Z68X-UD3H-B3, Socket-1155

Everything else;
Monitor - Samsung 27" LED SyncMaster S27B350 & Asus 24" VW246H
Mousepad - Corsair Vengeance MM600
Mouse - Logitech G600
Headset - Astro A40 2014 w/ mixamp pro
Keyboard - Razer Black Widow 2011
Controller - Xbox 360 USB controller

Everything is stock, nothing is overclocked.

HERE is the link of the event viewer. When my system crashes completely witch it rarely does, as mentioned, that kernel-power 41 event pops up. Not sure what it means myself, but you might

Rarely the system will decide to crash completely, similar to a BSOD. The only difference is that I can't use the reset-button at all, and the monitor isn't blue but instead black because they turn off. (More or less blinking to a permanent black, as when you're updating GPU drivers.)

This makes me think it is caused by the motherboard, PSU or GPU, although I think the first two of the three are most likely the cause.

I go to school so I wont be able to reply until after 3 PM at all.

English isn't my native language so there may be some typo's lurking around.

Thank you all in advance

Bump! I know it isn't really appreciated, but since the problem still persists I figured I should give it a try!

I have now scanned my computer with the programs you gave me and they did find some bad stuff that I have now removed.
I took three pictures, one when scanning the computer, one when testing "OBS" and one 10 minutes after testing "OBS".
The CPU usually stays somewhere around 40 degrees C, but it got pretty hot when trying OBS.

Now the CPU is running tad hot for my liking Hauk but not so bad it is likely to burn. Having said that the Tcase see this is set at 72.6C which to me is an indicator of what not to get near with the CPU temp. In other words it is the temp at which the CPU will shut down to prevent wrecking it.

So as a precaution I would be redoing the thermal compound Hauk and make sure the cooling is up to scratch. However doing that on a laptop is quite a fiddly thing to do and I suppose as long as you do not get those temps over the max's you show then it's ok.

Just one thing you can try is this.


What you can do is to check the air intake aperture and the"rad" and to do that shine a very bright light into the fan apertureand look through from the outlet grill
1. You will see if there is a lot of dust in the fan intake and fan blades and2. you will see if the "rad" is blocked in any way when you lookthrough from the outside.

Now to clean you can blow the dust out using compressed air but first makesure you insert something into the fan blades before you do - to stop the fanfrom spinningas spinning the fan withair will cause it to spin at much higher revs than it was designed for and canwreck the bearing.
The rad you can use those chenille wire play things to very gently clean therad from outside the machine and again blow the dust out. It is fiddly buteffective.
In my pic (just an example) you can see what is typically the set up for cooling and the light should be directed down into that fan and you look through the grill into the "rad" and dust, hair and crud should be cleaned out using the above.
But as in my ditty be very gentle doing this.

For posting pics mate just to make life easier for you read this.

I am actually not using a laptop, so I'll see what I can do
But is the CPU temperature likely to be the problem?

Oops my mistake mate I saw your specs and naturally went gung ho on that. So what machine are you dealing with? and what is the cooling arrangement because using the stock CPU cooler and some of the other methods are light years apart in performance ie stock - very basic and depends a lot on fast fan speeds and the liquid coolers that are more efficient because the liquid dissipates heat far more rapidly because there is more of it and it has a greater surface cooling area in the radiator. Some of the aftermarket air coolers are good but tend to be really on the very large side and heavy as well not to mention expensive.

Clue me in, what is a OBS?

I am dealing with a desktop, the specs are posted in #1. I am using the stock fan, but haven't overclocked the CPU so I figured I didn't need an aftermarket one. I'd love to get some liquid-cooling going, but I don't have any money to fix something like that at the moment.

'OBS' stands for Open Broadcaster Software. You can stream to webpages such as or

And did you want me to re-post the pictures as you linked me those tutorials?

Posting using that tutorial is the preferred way on this forum.
Many members including me will not go off site to see these things.
It's much safer for other members if you use the forms method.
I have no idea what is going to happen if I tick on those sites and I don't want to know.

Now I will go back to post #1 and start over. Maybe something will come to my brain.

Your English is fine.
I'm some what confused. What happens in 1/2 of a second is almost impossible to diag. After the 1/2 second are you having any other problems?

What I'm searching for is a problem you are having other than that 1/2 second thing.
We don't want to give wrong guidance because we don't understand clearly your problem.
